Hi bremen22,

Have you tried copying & pasting the Excel charts into your presentation, using Powerpoint's Paste|Paste Special>Paste Link option? That way, you shouldn't need any code to keep it in synch with the Excel data. Indeed, if the Excel workbook is open at the same time as the Powerpoint presentation is open, there will be no appreciable delay between the data in Excel being updated and the updates appearing in the presentation.

If that isn't suitable, can you attach a document to a post with some representative data (delete anything sensitive) and the code you're using? You do this via the paperclip symbol on the 'Go Advanced' tab. That way, it should be possible to quickly diagnose the problem.
